New PC wont power up.

[fvalls]

As far as I know, everything is hooked up the way it should be but the PC wont turn on. There is a blue light in the power supply switch, but when I turn on the PC nothing turns on. I have double checked all the wires and I believe that they are all connected correctly. Whats wrong? Is my motherboard dead? Is my power supply dead? What can I do to troubleshoot this?

If the out of the case build doesn't fix it, then post the parts of the build, make and model of everything including power supply.

I will try this today. Does it matter if I keep the motherboard in the case? I dont see why it would.

Yes. It's important to take it out of the case to ensure that it's not being shorted out.

As Shadow has said, it is very important to remove the motherboard. One of the most common reasons why a new build will not start is the motherboard grounding against the case frame.

I am a little nervous about the whole using a screwdriver part. Is there any other way to do this? Also, I have a XFX NFORCE 680I LT SLI INTEL SOCKET 775 DDR2. What two pins do I use? Is it the PWRSW RED 2-Pin? So when I turn on the power supply I am suppose to take a screwdriver and place it on top of the two pins and once the computer starts take the srewdriver off? Is there something else I can use?

The power switch on a computer case is known as a "momentary" switch, basically it only makes contact for a moment (usually the length of time your finger is depressing the switch).
Sometimes when I am working in a crowded case and need to momentarily short the power switch pins I use a spare motherboard, harddrive or optical drive jumper (they are all the same), if you are concerned about using a screwdriver tip try using a spare jumper.
You only need to short the pins for a fraction of a second as the moment you do short them the motherboard should start, whatever you use to short the pins, remove it immediately.
You then shut the machine down in the same way only this time you keep the pins shorted as long as it takes for the machine to shut down.

Edit. Do you know the serial number or product code of your motherboard? I need it to find the correct manual so I can check the power switch pins.
